However, it would be false to conclude that MacArthur never teaches Particular Redemption in the Study Bible notes.  For example, he makes a brief statement at Mark 10:45 affirming the doctrine:  "... Christ's substitutionary death on behalf of those who would put their faith in Him is the most glorious, blessed truth in all of Scripture ...".

One of his strongest affirmations appears at 1 John 2:2 where he writes...

for the whole world.  This is a generic term, referring not to every single individual, but to mankind in general.  Christ actually paid the penalty only for those who would repent and believe.  A number of Scriptures indicate that Christ died for the world (John 1:29; 3:16; 6:51; 1 Tim. 2:6; Heb. 2:9).  Most of the world will be eternally condemned to hell to pay for their own sins, so they could not have been paid for by Christ.  The passages which speak of Christ's dying for
the whole world must be understood to refer to mankind in general (as in Titus 2:3,4).  "World" indicates the sphere, the beings toward whom God seeks reconciliation and has provided propitiation.  God has mitigated His wrath on sinners temporarily, by letting them live and enjoy earthly life (see note on 1 Tim. 4:10).  In that sense, Christ has provided a brief, temporal propitiation for the whole world.  But He actually satisfied fully the wrath of God eternally only for the elect who believe.  Christ's death in itself had unlimited and infinite
value because He is Holy God.  Thus His sacrifice was sufficient to pay the penalty for all the sins of all whom God brings to faith.  But the actual satisfaction and atonement was made only for those who believe (cf. John 10:11, 15; 17:9, 20; Acts 20:28; Rom. 8:32, 37; Eph. 5:25).  The pardon for sin is offered to the whole world, but received only by those who believe (cf. 4:9, 14; John 5:24).  There is no other way to be reconciled to God.
